Title: Method and apparatus for real-time control
Inventor: CARRETTE GEORGE J
IPC: G05B13/02
Filed: 1990-05-31
Abstract: Abstract of the Disclosure Digital processing methods and apparatus for monitoring, controlling, and simulating industrial processes operate on data signals representative of process parameter values and generate response values representative of desired or requested process parameter values.  A knowledge base stores knowledge of the industrial process in the form of rules, and an inference engine applies the rules to calculate the response values.  A time-stamp value is assigned to each data signal, representing the time of receipt of each signal.  Currency evaluation elements, responsive to user-selected currency range values and the time-stamp signals, assign an expiration time value to the data signals and disregard data signals having an expiration-time value outside a corresponding user-selected currency range value.

Title: Telephone dial-inbound data acquisition system with demand reading capability
Inventor: WHITE DARRYL C
IPC: H04M11/00
Filed: 1992-06-11
Abstract: TELEPHONE DIAL-INBOUND DATA ACQUISITION SYSTEM WITH DEMAND READING CAPABILITY       Abstract A  telephone  dial-inbound  data  acquisition  system  with  demand reading capability.   The system has particular application for remotely reading utilitymeters.    A  remote  data  unit  (RDU)  dials  up a host computer on a periodicbasis.    The  RDU  is assigned a callback start time by the host computer.  TheRDU  calculates  an  actual callback time based on the callback start time and arandomly  generated  time delay.  The RDU dials up the host computer via a modemwhen  the local time, as shown by an on-board real-time clock at the RDU, equalsthe  calculated actual callback time.  Meter reading data is then transferred tothe  host  computer.    The  RDU also contains circuitry for detecting a pollingsignal  generated  by the host computer.  Upon detection of this polling signal,the  RDU  immediately  dials  back the host computer and transfers utility meterreading  data to the host computer.  The RDU will also immediately dial back thehost  computer  if  an  alarm  condition occurs, e.g. tampering or a low batterycondition.    The  RDU  contains  circuitry  for  characterizing the on-hook andoff-hook  electrical  characteristics  of  the telephone line to ensure that theRDU does not interfere with normal operation of a customer's telephone line.

Title: Nonwoven multicomponent polymer fabric and method for making same
Inventor: PIKE RICHARD D
IPC: D04H1/54
Filed: 1992-11-30
Abstract: A process for making nonwoven fabric including the steps of meltspinning continuous multicomponent polymeric filaments, drawing the multicomponent filaments, at least partially quenching the multicomponent filaments so that the multicomponents have latent helical crimp, activating the latent helical crimp, and thereafter, forming the crimped continuous multicomponent filaments into a first nonwoven fabric web. By crimping the filaments before the web formation, shrinkage of the web after formation is substantially reduced and the resulting fabric is substantially stable and uniform. In addition, the resulting fabric can have a relatively high loft. The crimp activating step can include heating the multicomponent filaments and preferably includes drawing the multicomponent filaments with a flow of heated air to activate the latent helical crimp.      The resulting fabric can form relatively high loft materials useful as a fluid management layer for personal care absorbent articles or can form cloth-like fabric useful as cover materials and garment material. In addition, a nonwoven fabric comprising continuous single and multicomponent filaments and proces for making same are provided. Still further, a multilayer nonwoven fabric with continuous multicomponent filaments and process for making same are provided. The degree of crimp in the filaments can be varied from layer to layer to produce composite webs with particular fluid handling properties.
